I agree with the last reviewer, Joe and Peggy bickering is something to see... Not happy campers. May have been an attempt to develop her character, now revealing she is the widow of a cop and a young mom. Bottom line, a "bad day" for both Mannix and Peggy. One interesting note; Peggy calling him Mr. Mannix? That would be dumped soon, and with good reason.
This time around, Joe has the tough luck task proving a man he helped convict for embezzlement is innocent. Prime example of one of those "complex" episodes you literally take notes on. Sutton Roley directed, who would do many more stories, and gets what he wants from a great cast. John Colicos (usually playing villains) has a sympathetic role for a change. He would appear in about one episode per season. For STAR TREK buffs, best known as the first Klingon, which he also assisted in creating facial features and the costume.
Cloris Leachman plays his ex-wife, and in a very good dramatic role. What many don't know is she appeared in one of the first tv detective shows called CHARLIE WILDE as his secretary, around 1950 in New York. Great trivia question.
Veteran Marie Windsor plays the wife of Mr. Timpkins (Paul Stevens), wearing a blonde wig. Look closely or you will not recognize her. She rivaled Beverly Garland in noir and sci fi films of the 50s and was always popping up on tv.
There's a crazy skid row bar scene in which Joe passes out. Among the patrons is Noble "Kid" Chissel, playing a bum, a 1930s boxing star who would do other bits on the show. We also get a glimpse of Peggy's son, Toby, played by Mark Stewart, a hero to all of us kids back in the day. Some bios indicate Stewart, later called Stew, became a musician as an adult.
Watch closely, or you'll miss something. SEASON 2 EPISODE 9 remastered CBS/Paramount dvd box set. 6 dvds. Released 2006. Cool purple-ish cover with Joe and Peggy.
